Nine Mile Creek Aqueduct is a restored stone and wood aqueduct of the Erie Canal over Nine Mile Creek in Camillus, New York. It was built in 1841 and was listed on the National Register of Historic Places in 1976. The towpath part of the structure has four arches of 30 feet (9.1 m) each. The structure was built of stone joined by a marine cement that was relatively new at the time, but which has endured well. In August 2009, boats traversed the restored aqueduct for the first time since 1917. * Progress of restoration as of May 25, 2009 * Timbering * Through the towpath archways
